My latest crystal, from a failed batch which i put in a beaker and used as container to drip remainders of solvents, acids andsoforth. After some weeks i needed the beaker and while cleaning it, i found these.

Now i want to make these on purpose but how... without using loads of beakers as a waste bin

I never so 3cmc in flowers like crystals

Result of 150g mmc 1:1 watter. 80celcius solution, put in towels at ~24c. after 12h got ~38g crystals like these, mother liquid must be evaporated to get rest mmc. I dont know what i did, becouse second try of this method was not succesful at all. But i Want to get crystals like these any advises?

You need to understand the theoretical yield (how much acid you used) and keep the same proportions for the product, water and temperature so that the result is stable.

Okay.. Sometimes its differs, becouse I cant achieve full control of reaction(time to time its going better), but mostly for 100g bromo 40ml 28%hcl

But what does crystallization have in common with recrystallization. I already have white, no odour crystals but suggar size and want to make bigger - "like flower". today i got it again flower like. but from 80g got ~20g flowers then put to fridge and all my "flowers" now in the tiny snow flakes

And again 1:1 watter, towels slow cooling.. and got these. clean but nor nice I want to get crystals like other time... Whats wrong guys?

 

[William D.]

This product is even more convenient to use, even if you don't like the size of the crystals.

 

[SunDay]

I agree, but sometimes I need glass like crystals. And for myself I want to do it perfect, I want to learn how to do it even I dont need it

Use hot solvent, and do not let the mixture quickly become cold. You can use less solvent and control the cooling temperature. Then you can get crystals larger and faster. But with this method and a small amount of solvent, do not use open containers (you need to avoid liquid evaporation and create pressure). These are the foundations of a faster method, but there are others (but I take more time).
